The delegation, led by Chairman of the Iranian Parliament’s National Security and Foreign Policy Commission Alaeddin Boroujerdi, arrived in Beirut on Saturday after a visit to Syria.
During the meeting, Nasrallah and Boroujerdi discussed the latest political developments in the region.
The senior Iranian lawmaker also held talks with Lebanese Parliament Speaker Nabih Berri.
After the meeting, Boroujerdi said he and Berri underlined the need for a Syrian-Syrian dialogue for an end to the conflicts in Syria.
He added that Iran and Lebanon share the view on the necessity of unifying efforts to counter terrorism.
Syria has been gripped by civil war since March 2011 with various terrorist groups, including Daesh (also known as ISIS or ISIL), currently controlling parts of it.
According to a report by the Syrian Center for Policy Research, the conflict has claimed the lives of over 470,000 people, injured 1.9 million others, and displaced nearly half of the country’s pre-war population of about 23 million within or beyond its borders.
